Three four hairy species are quite confusing and we have to follow the following keys from Flora of Peninsular India as below:
36 Leaves elliptic lanceolate or oblong, more than twice as long as broad
38 Stipules prominent ovate lanceolate or lanceolate
39 Stem with spreading hairs
41 Pods slightly exserted, 15-20 seeded …. C.hirta
41 Pods much exserted , 20-35 seeds
42 Leaves villous beneath; bracts often 3 lobed; pods subsessile ….. C.mysorensis
42 Leaves appressed pubescent beneath; bracts simple; pods shortly stalked …. C.ferruginea
38 Stipules minute or 0.
43 Pods as long as or shorter than calyx
44 Calyx to 0.8 cm long; upper two lobes connate except at tip; pods globose … C.linifolia
44 Calyx to 2.5 cm long; lobes connate at base only; pods oblong …. C. calycina
Erect branched herbs, silky pubescent. Leaves to 5.5 x 1.5 cm, oblong, obovate, apex obtuse, apiculate, base cuneate, pubescent; petiole 1 mm, stipule 0.5 cm, lanceolate, ciliate. Racemes lax, 6-8 flowered; flowers yellow, pedicels 0.5 cm; sepals connate at the base, 1.5 cm, lanceolate, tomentose; keel sepal linear; standard petal 17 x 8 mm, orbicular; wings 10 x 5 mm, oblong, obtuse; keel united, 1.5 cm long, enclosing the stamens and pistil; anthers dimorphic, larger 3 mm, smaller 0.3 mm; ovary 4 mm, oblong, style constricted at the bent, 1.3 cm long, puberulus, stigma oblique.

Crotalaria prostrata Rottler ex Willd. ??
Looks different from Crotalaria prostrata Willd.
Keys in Flora of Bhutan at Crotalaria lead me to (15. C. ferruginea Bentham), 16 (16. C. humifusa Bentham) & 17 (17. C. acicularis Bentham)
I am ignoring the following on further checking these at
Crotalaria humifusa Benth. as per details herein &
Crotalaria acicularis at FOC illustration, POWO Florida plants YDHVN
I think it is close to Crotalaria ferruginea as per GBIF High resolution specimen BGO YDHVN
Thank you …! Crotalaria ferruginea Graham ex Benth.

I also think so. Pl. check comparative images in efi site.
Its Crotalaria L.
Yes it is already mentioned in the caption that it is Crotalaria but which one?
Could not find a match at comparative images at Crotalaria
Does look like Crotalaria alata to me
Has this ID not been considered?
Crotalaria alata has flat, rather winged stem, isn’t it ?
I tried again, but could not find match as per comparative images at Crotalaria
Please have a look at Crotalaria triquetra. It looks close.
I am not sure … if it matchs !
Looks different from images at Crotalaria triquetra
Also does not have any distribution as per ILDIS
It is late evening, I collected during my posting at Sikkim and it is C. ferruginea, immediate response and am confident, please do match and intimate.
